Maths in php

[MemphiS]

Example:

 

<?php
$total_rows = mysql_num_rows(mysql_query("SELECT `id` FROM `users` WHERE `accepted` = '1'")); // 1 rows
$total = mysql_num_rows(mysql_query("SELECT `id` FROM `users`")); // 2 rows
$roundoff = round($total_rows / $total);

echo("$roundoff");

 

What i want this to get at is 50% as there is two "total" rows and only 1 accepted. Not to sure how i should code it. Thanks for any replys

[only one]

thats simple..

 

$roundoff = round($total_rows / 100) * $total;
